FLOOR CON STRUCTION Application ledAugust 14, 1922. Serial No. 581,752.

To all whom it may oon-cem.'

Be it known that I, THOMAS J. FOSTER, of Ithe United States, and resident Of Ridgewood, Bergen County, State of New Jersey, have made a certain new and useful Invention Relating to `Floor Constructions, of which the following is a specification taken in connection with the accompanying drawing, which forms part of the same.

' This invention relates especially to floor constructions of a fire proof or semi-fireproof character and aims to provide a lightweight water tight and sound-proof Hoor at a minimum cost.

In the accompanying drawing showing in a somewhat diagrammatic manner anA illustrative embodiment of this invention.

Fig. 1 is a vertical sectional View of the construction, and

Fig. 2 is an enlarged section showing a modified form thereof.

The floor beams 1 are preferably of the skeleton or lat-tice lweb typein which the expanded'webs may comprise the web di- 'agonals and these beams may be supported on or secured tothe--girders in any suitable way andy spaced apart at distances of two o'r` three feet more. or less between centers.-

:Combined ceiling and floor support st-rips or elements may be applied to these beams and sheets of sound and heat` insulating non-combustible or ireproof material such as sheet rock, plaster board or other still'y more fireproof asbestos board mineral compositions may be used and may be cut in strips of such width 4as to extend between the centersof adjacent beams for example. These sheets or strips 8' are preferably supported on intermediate centering boards 7 durin the construction-of the floor panels and it is giglily advantageous to support these centering boards on centering supports such as 4; which may extend through any suitable. Openings in these skeleton beam webs and thus have considerable length soas to more effectively insure the desired leveling up of this floor centering. For this purpose suitable wedges 5 which may have tapering, lower faces cooperating with the upper or lower' angles between the beam diagonals 3 may be driven or forced beneath these centering supports 4 of any suitable height and in some cases support-lng blocks 6 may extend down to the lower beam flange and support these lidiied. These nailin wedges or the centering supports directly in some cases.

It is usually advantageous to apply a layer is applied. Nailing stripssuoh as 12 of wood or composition which may have the aligning or retaining nails 13 projecting "therefrom may be put in place and effectively held down by this waxy binder especially if these nailing` strips are put in place before the binder has cooled or sostrips may, if desired, be coated with this or otherwise water-proofed by appropriate treatment before being put in place in the floor structure. In some cases also clips such as 16 may extend at suit-able distances up from the upper flanges 2 of the beams around which the lower portions 17 of these clips may be secured 'so as to support the expanded metal or' other'reenforcement 11 which .may be' used in these floor panels. The floor material 10 such as cement concrete or other suitable composition (hereinafter referred to indiscriminately as cement, compositioin or concrete) may be poured or cast into the panels and, if desired, leveled up in connection with the nailing strips 12 which may act asvscreeds in leveling this Hoor material 10 which'adhesively engages the waxy held in theI desired position. A cement composition iloor of this character two or three yinches thick more or'less is quite thoroughly lireproof when no nailing strips are used and even with the usual narrow nailing strips 12 the lloor body is substantially ireproof and would -pia'ictically prevent the penetration of lire upv through vthe floor from the room below. Ast shown inl Fig. 2, these nailing strips may be used to secure in position the {iooring boards 14 which maybe nailed to these strips as by nails 15 at the desired intervals. Y

When the floor panels have set and hardened sufficiently the centering may be readily removed and for many purposes the skeleton or lattice web beams may be left in exposed position on the ceilingwhere they are much Water-proof binder` binder so as to be thereby less objectionable in appearance becauseV of their light lattice or grillework 'appearance than ordinary steel beams would be. If desired, however, these floor beams of skeletonweb or other construction may be enclosed as shown in Fig. 2 and for this purpose metal or other casing members may c be used to enclose and conceal the beams.

` bodiments, forms, proportions,

Specially shaped blocking stri s 18, 19 may be secured adjacent the beam anges in any suitable way and then the metallic or other beam casing 20, 21 may be nailed or other,- wise secured in place as by the nails A23, 24 which may also secure the molding strips 22 next the ceiling thus producing the same effect as exposed wood beams in a beamed ceiling. If. desired,` however, i the .beams may be concealed by a hanging ceiling of ireproof or other construction and as shown in Fig. 1,`the supporting strips 25 may be secured to the beam flanges as by the wire ties 26 after the centering has been removed and then the plaster board or other composition material 27, preferably of non-inflammable vor reproof construction, may be nailed or otherwise secured to these supporting strips so as to. form a substantially conf tinuous level ceiling, if desired.

This invention has been 'described in connection with a number of illustrative emsizes, parts and methods of connection anduse, to the details of which disclosure the invention-1s t not of course to 4be limited since what is claimed as new and .what 4is desired' to be secured by Letters Patent is set forth in the appended claims. v In the claims the word beams is used to describe rolled or fabricated ,beams or joists, either made in one piece or built up of several pieces, such as are commonly used for floors for dwellings, apartments and oflice buildings; and the word flange is usedfto designate the top or bottom chord member or members thereof.
